I’ve been vaping on a Nautilus X for a couple of days and I really like it with the extension and 1.8 ohm coil. Not much airflow (at all), but plenty for MTL and the flavor is excellent. But, it’s a pricey tank once you get the extension, which is required IMO.
I also just got a Cubis Pro, and I REALLY like the design, airflow, and feel of this tank… but I also REALLY hate all of the coils it comes with. They are all gurgly, spitty, and just very intermittent. I’ve got some 1.5 ohm Claptons and SS316 1.0 ohm coils on the way, so hopefully they will work much better and I won’t have to throw the Cubis against a wall as hard as possible. If it works with those coils, it will be a nice inexpensive tank.
I also have a Vapefly Nicolas on order, which looks to be another nice inexpensive tank, assuming replacement coils don’t become unobtanium in the near future.
